Real-time monitoring and mapping of ablation lesion formation in the heart |
(57) A method is provided for ablating tissue in a heart of a subject during an ablation
procedure. The method includes applying a local treatment to the heart at a plurality
of sites designated for ablation. At each respective site, a parameter is sensed that
is indicative of a level of ablation at the site. The method preferably includes displaying
a map of the heart, and designating, on the map, during the ablation procedure, indications
of the respective levels of ablation at the sites, responsive to the respective sensed
parameter.
